Concepts overview

Meerkat Recall connects claims to the evidence that supports them. It keeps the original source, the extracted interpretation, and the current answer as separate records so that a reader can ask both what do we know? and why do we believe it? Consider a synthetic project note: “Mara joined Northstar Labs in March 2026.” That sentence can support an employment relationship and a dated event. It does not, by itself, prove that Mara still works there today.

From evidence to an answer

The diagram shows the graph-ingestion path. A source can also stop after metadata processing or document retrieval. Background work is asynchronous: accepting an ingest request does not mean its graph or wiki page is ready.

​

What each record means

Extraction is interpretive. The table illustrates possible records, rather than promising an exact number of rows or identical model output on every run.

​

Identity, evidence, and truth are different decisions

Three questions arise when another note says “Mara now works at Cedar Works”:

1. Identity: is this the same Mara? Entity resolution uses names, identity keys, type compatibility, and, when configured, disambiguation.
2. Vocabulary: does “works at” mean the canonical works_at predicate? Predicate registration and alias governance answer that question.
3. Truth: did Mara change jobs, hold two roles, or appear in an ambiguous source? Truth maintenance evaluates the competing claim values and their configured semantics.

A high extraction confidence addresses what the source says. It does not settle identity or prove that the statement remains true.

​

Isolation and visibility

Records belong to a space. Within that space, security envelopes determine which records a principal can read or modify. Truth maintenance and knowledge views also preserve security boundaries: evidence from a more restricted envelope cannot silently become a less restricted answer. A missing search result can therefore mean that a record is unauthorized, not yet processed, excluded by a status filter, or absent. Inspect the relevant status and use the same principal and space when diagnosing it.
